Selling/mailing Ammo

This is a discussion on Selling/mailing Ammo within the Defensive Ammunition & Ballistics forums, part of the Defensive Carry Discussions category; If I posted somewhere ammo for sale does the transaction have to go through a FFL?
Also how do you mail the ammo, lea gal ...

Is this ammo you bought and don't need, thus trying to get rid of it? Got surplus and trying to make a buck? Ammo you reloaded?

A one-time sale is no big deal--generally. Reloading with intent to sell requires licensing. Planning on making some side money selling any ammo may require a business license if nothing else. Other than a one-time sale, anything repeated can put you into the "business for profit" category.
